In figure:1- built-in splitters;2- economizers;3- evaporators;One section of 4- superheaters;Two sections of 5- superheaters.
Specific implementation mode
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
It is shown in Figure 1, a kind of sintering exhaust-heat boiler device, including the boiler body 100 that is vertically arranged, the boiler sheet The bottom of body is gas inlet 101, and upper end is exhanst gas outlet 102, upward from the gas inlet, is disposed with built-in separation Two section 5 of device 1, economizer 2, evaporator 3, one section 4 of superheater and superheater;The economizer, evaporator, one section of superheater with And two sections of superheater is connect with drum 6.
Specifically, the pipeline of the economizer 2 is connect by connecting tube 21 with drum, to be discharged into the water after heating to drum In, the evaporator 3 is connect with drum by the first pipeline 31 to receive the water from drum, and will again by the second pipeline 32 The steam of water and formation after secondary heating is sent in drum, and the import that one section of the superheater passes through third pipeline 41 and drum Connection can be hot by the steam (vapor) outlet connection of one section of superheater to receive the steam from drum, and after heat exchange The high-temperature steam of generation is discharged the vapour-discharge tube 43 that one section of device, the steam inlet 52 (import) that two section 5 of the superheater It is connect with drum by third pipeline 41, can equally receive the steam from drum, and after heat exchange, pass through overheat The high-temperature steam of generation is discharged the vapour-discharge tube 51 that two sections of device, wherein the vapour-discharge tube 51 that two sections of the superheater with The vapour-discharge tube 43 that one section of superheater is connected, in addition, the steam outlet of one section of the superheater also by with superheater The steam inlet 52 (import) of two sections of the 4th pipeline 42 that one section of vapour-discharge tube 43 is in parallel and superheater connects, so as to It realizes and two sections one section of high-temperature steam formed of superheater is reheated by superheater, realize the temperature higher of steam, be then discharged out Superheated steam.
When work, flue gas flows from bottom to top through flue to exhaust-heat boiler flue gas import, flue gas, and stream passes through built-in separation Two sections of device, economizer, evaporator, one section of superheater and superheater, are finally discharged into chimney.Exhaust gas temperature is about 100-220 DEG C, flue-gas temperature drops to exhaust gas temperature from 380/330 DEG C, and the heat released is used for that water is made to become steam.Into waste heat boiler Water supply, temperature is about 42-126 DEG C or so, be introduced into lower part setting economizer, water absorbs heat in economizer to be made Water temperature rises, and water temperature is raised to the saturation temperature under slightly below drum pressure, just leaves economizer and enter drum.Into the water of drum It is discharged into evaporator again, is returned in drum using steam mixture is formed after evaporator and flue gas heat exchange, forms cycle, drum In steam enter two sections of one section of superheater and/or superheater, through two sections of one section of superheater and/or superheater with high-temperature flue gas again Secondary heat exchange forms high-temperature steam discharge.
Isolated operation may be implemented with two sections of superheater in one section of the superheater, can also parallel synchronous operation, can also Series operation can be realized by the way that corresponding switching valve is arranged on pipeline by switching control
The built-in splitter 1 is located in the gas inlet socket of the boiler body, for multiple parallels up and down Rectangular-shaped separating tank, the direction that flue gas enters, multiple separating tank parallel arrangements are directed toward in the notch end of the separating tank At multilayered structure, every layer of separating tank is mutually evenly-spaced, and is staggeredly arranged between the separating tank of levels.
The lateral cross section of the rectangular-shaped separating tank is rectangular-shaped, i.e., groove profile is rectangular channel.
Wherein, the both ends of the separating tank are connected with the inner wall of the respective side of the gas inlet socket, such as can be It is welded to connect.
Since separative efficiency is relatively low when the depth-to-width ratio of separating tank is too small, since collision reaction and the back-mixing of particle act on, hold It is relatively low to easily cause separative efficiency, it is preferred that the depth-to-width ratio value of the separating tank of the present apparatus is 1.2;
When specific arrangement, when laterally opposed pitch (separating tank lateral distance) increases, the separating tank often arranged then accordingly subtracts Few, total separative efficiency reduces;When laterally opposed pitch is too small, although separating tank increases so that separating area increases, Crack air velocity between separating tank increases, and causes the back-mixing of particle and volume to inhale serious, separative efficiency improves less, preferably , the laterally opposed pitch value of present apparatus separating tank is 2.4;Longitudinally opposed pitch (distance of neighbouring two separating tanks) After optimizing relatively, it is 1.65 to choose best longitudinally opposed pitch.
The utility model is the boiler body smoke inlet positioned at sintering exhaust-heat boiler, can be divided using inertial separation method It is to complete solid using carrying the air-flow of the solid particle possessed original inertia in impingement baffle from solid particle The separation of grain.
The utility model can be applied to waste gas residual heat recycling electricity generation system, especially steel sintering cooling residual heat electricity generation system Waste heat boiler built in terms of exhaust gas and dust separation.When work, comes from hot mine cooler flue gas and the flue gas in air port is taken to be sintered certainly The bottom smoke inlet of the gas inlet socket of waste heat boiler enters in sintering exhaust-heat boiler, after groove profile shape separator, warp The exhanst gas outlet on sintering exhaust-heat boiler top is discharged, and realizes the separation to the middle particulate matter of flue gas, detaches flue gas after solid particle It is discharged from exhanst gas outlet, particulate matter is blocked in outside waste heat boiler.
In order to adapt to load variations, heat-resistant and wear-resistant material shape can be used in the inner wall of present apparatus separating tank and gas inlet socket At coating.
The utility model has the following advantages:
(1) separator is merged into design with sintering exhaust-heat boiler, accomplishes equipment integration, simplifies sintering exhaust-heat boiler cloth Form is set, the radiation loss of pipeline is reduced, saves construction area area.
(2) superheater uses subsection setup, can cut out of service, the furnace outage time after reduction abrasion.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change The scope of protection of the utility model is also should be regarded as into retouching.
